"As a major Linux vendor, one might expect that Red Hat's new Red Hat Enterprise Virtualization for Servers solution would be able to run on Linux servers. You'd be wrong. Not only is that not the case, but the Management Server piece of RHEV, which provides virtualization management capabilities, requires users to be running Microsoft's Windows Server. That's no typo: A Linux vendor is requiring its users to run one of its key new products on the rival, closed source Windows operating system. According to Red Hat, the plan is to have a Linux version ready by some point in 2010. But in the meantime, Red Hat customers who want to run the virtualization manager must purchase or already own a Windows server."
